----------------------------------------
Summary: In typical setups, DefaultArtifact copies the same maps
over and over again
Key: MRESOLVER-586
URL: https://issues.apache.org/jira/browse/MRESOLVER-586
Project: Maven Resolver
Issue Type: Improvement
Components: Resolver
Affects Versions: 1.9.21
Reporter: Guillaume Smet
h2. Context
This is part of some work we are trying to do to reduce the build time usage
memory of Quarkus.
We discussed this a bit with Tamas.
While this doesn't constitute a fix for our main issue, it should be an easy
win.
h2. Problem
We have a BOM with 2000+ entries and in `ArtifactDescriptorReaderDelegate`, the
managed dependencies are copied to the descriptors using the `convert` method
that in turn will create a new DefaultArtifact.
Most of these DefaultArtifacts contain a copy of the very same
`type.getProperties()` as they don't have specific artifact properties.
Improving the DefaultArtifact#merge() method to avoid the copy when the
artifact doesn't have any specific properties would already be an easy win.
PR to come.
